Safety Tips
Q: My battery is lithium battery, which battery setting shall I use?
A: please use FLOODED.
Q: will the system discharge my battery after sunset?
A: No. The charge controller avoids discharging from battery.
Q: Can I use my own controller, or can I use MPPT charge controller?
A: Yes, if you would like to do so, please remove the charge controller and use the solar panel with MC4 connectors to connect
your own controller.
Q: I connect the kit with my battery with red clamp to Positive and black clamp to Negative, why the lights of charge controller are
not on?
A: we suggest charging your car battery for the kit’s test. And then test your solar panel’s open circuit voltage and battery’s
voltage. If the solar panel open circuit voltage is good and the battery’s voltage is lower than rechargeable voltage, the battery
should be recharged some other way or replaced before charging with the solar panel.
Q: Can I use the solar panel to jumpstart a drained battery?
A: No, the drain car battery has lower voltage than what the kit could recharge. Therefore, please jump start the battery and
make sure the battery is high enough, then charge it by the solar panel.
Q: Can I use the solar panel to avoid my battery drain?
A: Yes.
Q: My RV has a Zamp solar plug or other types of plugs, how do I use this solar panel kit?
A: You will need to refer to the RV user manual and find out what kind of adapter you may need. Most adapters are sold on
Amazon. Please contact support@acopower.com if you can’t find what you need.
Q: The solar panel kit has the correct voltage reading but it won’t charge my generator.
A: Please check the voltage rating of your generator, it might be rated at 24V and this solar panel kit is only for charging 12V
batteries. Another possibility is that the generator is already fully charged.
